Method Detail

deregister

public void deregister(Watch... watches)

Description copied from interface: WatchRegistry

DeRegisters a Watch from underlying collection and closes the Watch

Specified by:

deregister in interface WatchRegistry

Parameters:

watches - The Watch to deregister

See Also:

WatchRegistry.deregister(org.rioproject.watch.Watch...)

closeAll

public void closeAll()

Description copied from interface: WatchRegistry

Closes all WatchDataSource instances

Specified by:

closeAll in interface WatchRegistry

See Also:

WatchRegistry.closeAll()

register

public void register(Watch... watches)

Description copied from interface: WatchRegistry

Registers a Watch to underlying collection

Specified by:

register in interface WatchRegistry

Parameters:

watches - The Watch to register

See Also:

WatchRegistry.register(org.rioproject.watch.Watch...)

addThresholdListener

public void addThresholdListener(String id,
                                 ThresholdListener thresholdListener)

Description copied from interface: WatchRegistry

Add a ThresholdListener. The ThresholdListener will be added as a ThresholdListener to any ThresholdWatch instances that match the ThresholdListener when the ThresholdWatch is registered using the register method

Specified by:

addThresholdListener in interface WatchRegistry

Parameters:

id - The identifier to match

thresholdListener - The ThresholdListener to add

See Also:

WatchRegistry.addThresholdListener(java.lang.String, org.rioproject.watch.ThresholdListener)

removeThresholdListener

public void removeThresholdListener(String id,
                                    ThresholdListener thresholdListener)

Description copied from interface: WatchRegistry

Remove a ThresholdListener. The ThresholdListener will be removed as a ThresholdListener from any ThresholdWatch instances that match the ThresholdListener

Specified by:

removeThresholdListener in interface WatchRegistry

Parameters:

id - The identifier to match

thresholdListener - The ThresholdListener to remove

See Also:

WatchRegistry.removeThresholdListener(java.lang.String, org.rioproject.watch.ThresholdListener)

associateThresholdListener

protected void associateThresholdListener(Watch watch)

This method will associate a Watch to a ThresholdListener, iff the Watch is a ThresholdWatch and the Watch objects classname is found in the table

Parameters:

watch - The Watch to associate

findWatch

public Watch findWatch(String id)

Description copied from interface: WatchRegistry

Returns a Watch that matches the provided id

Specified by:

findWatch in interface WatchRegistry

Parameters:

id - The watch id to match

Returns:

The first Watch that matches the input id. If there is not a matching Watch, this method returns a null

See Also:

fetch

public WatchDataSource[] fetch()

Description copied from interface: WatchRegistry

Returns an array of WatchDataSource objects which provide a reference to an implementation of WatchDataSource.

Specified by:

fetch in interface WatchRegistry

Returns:

An array of WatchDataSource objects. If there are no WatchDataSource objects, this method returns an empty array

See Also:

WatchRegistry.fetch()

fetch
